| 221 | Articulated car brake system | US225723 | 1981-01-16 | US4346790A | 1982-08-31 | Robert B. Morrison; James T. Wade; Robert E. Zimmerman |
| A handbrake arrangement for railroad freight cars is disclosed that will connect a mechanical handbrake operating mechanism to the brake equipment (brake beams and brake shoes) on 2, 3, or more trucks on the same freight car. It is especially useful on articulated freight cars consisting of multiple units in order to satisfy handbrake power requirements required by industry and Federal regulations, but a similar arrangement may be used on special purpose cars having a multiplicity of trucks. On an articulated car, consisting of a number of units, there is a multiplicity of trucks and because of the size and weight characteristics of the car, it is desirable to connect the handbrake mechanism to a number of the trucks in order to provide adequate handbrake power. A relatively simple mechanical handbrake mechanism for providing adequate braking power to a series of lightweight short articulated interconnected cars consists of a series of rods, levers, and slack adjusters interconnecting two or more trucks to the handbrake operating mechanism. | ||||||
| 222 | Friction pad assemblies for rail vehicle brakes | US108671 | 1979-12-31 | US4343382A | 1982-08-10 | Gerald A. Ottewell |
| A friction pad assembly for rail vehicle brakes comprises a pad of friction material carried by a rigid backing plate, and the backing plate is detachably mounted on a shoe. A keeper is provided which includes a clamping member pivotally mounted on one end of the shoe. The clamping member has a clamp face which acts on one end of the backing plate to urge the backing plate into engagement with the shoe. The clamping member is urged into an operative clamping position by a wedge which is releasably driven between the clamping member and a relatively stationary surface in a block which is either integral with, or releasably attached to, the shoe. | ||||||
| 223 | Dual braking system for a mine locomotive | US838291 | 1977-09-30 | US4151898A | 1979-05-01 | Albert R. Lawson |
| This disclosure is directed to a mine locomotive braking system having an independently operated back-up braking capability, responsive within a matter of several seconds in stopping power and adaptable for retrofit to virtually any existing mining locomotive braking system to form a combination having the aforementioned capabilities in combination with an existing manually operated mechanical braking device usually requiring either physical strength or weight, viz., manually dependent physical force, on the part of the mine locomotive operator to force the arcuate brake shoes in contact with the outer wheel surfaces, thus making it susceptible to extended stopping times. The system is operated by a series of push buttons; the actuation of which operates a hydraulic mechanism whose output portions cause pressure to be applied upon a brake bar by cylinders thereby causing motion of the bar which in turn operates brake shoes which apply direct pressure to the locomotive wheels. A change of direction mechanism is employed to pivotally change direction to handle the rear wheels (or front wheels) as the case may be. | ||||||
| 224 | Brake rod support arrangement for railroad cars | US785869 | 1977-04-07 | US4079818A | 1978-03-21 | Osvaldo F. Chierici |
| A support arrangement for brake rods of railroad car brake rigging comprising a U-shaped support member suspended from the underside of the car, a slotted sleeve snap fitted on the brake rod and located to rest on the bight portion of the support member, with the slot facing upwardly, and a retainer member comprising a shank portion received in said slot and having its end portions extending beyond the ends of the sleeve and enlarged to embrace the upwardly facing side of the brake rod on either side of the sleeve slot, with the retainer member end portions being bonded to the brake rod. The sleeve is formed from an ultra high molecular weight polymer material that is of dry self-lubricating nature and resists adherence thereto of foreign materials and serves as a sound deadener and energy absorber. Such material is also characterized by its polishing action on the brake rod support surface it rides on to reform same to define a mirror finish that substantially inhibits further wear on the support during use. | ||||||

| 227 | Brake beam and sectionalized brake head therefor | US44376674 | 1974-02-19 | US3907078A | 1975-09-23 | MEANS DONALD C |
| This invention relates to a novel brake beam that is slidably supported by a pair of guide feet, one integral with each end thereof, and has inboard of each guide foot a sectionalized brake-shoe-carrying brake lead thereby enabling replacement of one or more sections of a break head should breakage or wear of a removable section occur, thus effecting a substantial reduction in the cost of repairing a damaged or worn brake head. Furthermore, the structural configuration of this novel brake beam is such as to enable transversely mounting thereon a hydraulic-pneumatic master cylinder or some other suitable type of brake-beam-actuating cylinder, and also the mounting, adjacent each end of the cylinder, of a fulcrum means for a hand brake lever.

| 228 | Force-transmitting device | US39743573 | 1973-09-14 | US3830061A | 1974-08-20 | SEVERINSSON L |
| A force-transmitting device moves a rod into a compressible medium in an expandable cylindrical casing moving axially within a tube to deliver a force upon movement into contact with a load so that when the casing encounters a load the medium expands the casing and frictionally clamps it within the tube.
